SOAP CAKE.

SPECIFICATION forming part of Letters Patent No. 651,954, dated June 19, 1900.

- AppIication filed March 9,1900. Serial No. 7,981. (No model.)

To aZZ whom, it may concern.

Be it known that I, LEOPOLD S. SAMUEL, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Soap Cakes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to'certain improvements in that class of soap cakes represented by those described and illustrated in my prior patents of the United States, No. 549,330, dated November 5, 1895; No. 555,663, dated March 3, 1896; No. 581,920, dated May 4, 1897, and No. 606,879,- dated July 5, 1898, the objects of the present improvements being to enable a greater body of medicament to be interposed between the sections, where it will be constantly exposed as the cake wears away, and curative effects of said medicaments, even when the cake is first used, will follow upon such use; to enable the sections to be held apart a suitable distance to permit the introduction of the desired layer of medicament or medicated matter therebetween; to facilitate the work of supplying the cake with such medicated matter, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description'of the working parts.

The invention consists in the improved soap cake and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses of theclaim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure l isa plan of the improved soap cake. Fig. 3 is a side view of the same preliminary to the introduction of the medicament. Figs. 4 and 5 are inside face views of the sections between which the medicament is held. Fig.

' 6 is a perspective View of 'a modified form of Fig. 2 is an end elevation of the same.

the cake, the sections being separate and ready to be placed together to inclose, or partly inclose, the medicament. Fig. 7 is a plan, and Fig. 8 a section, on line x of Fig. 7, of the said modified form of cake complete.

In said drawings, a 17 indicate sections or blocks of saponaceous matter adapted to be joined together, their contiguous faces being provided with a projection or projections a and correspondingly-shaped recess or recesses 12, adapted to fit into one another, so as to hold said sections in proper relative position when fastened by cementitious matter or otherwise.

Upon examination of Fig. 3 it will be seen that the projections a are longer than the corresponding sockets in the opposite section are deep, and consequently when the sections are placed together an open space cl of considerable width is formed between the sections, into whicha thick layer of the medicated matter can be inserted. This layer (marked 6 in Fig. 2) extends through the cake and presents, at the peripheral edges of the cake, a contact-surface forthe hands from which a considerable amount of medicament can be applied to the fiesh with healing effect while washing.

The medicament may be compounded with saponaceous matter having an affinity for the material of the soap-sections a b, or may be compounded with cementitious matter other than that which is of a soapy nature, or the sections may be joined together with sapona 'ceous or cementitious matter and the open chamber or space at filled with the medica ment or other useful matter to form the ex= posed layer.

I am aware that various modifications may be made in the arrangements of parts without departing from the spirit or scope of the invention, and I have illustrated one of such modifications in Figs. 6, 7, and S, where the sections a b are held apart by a block of soap adapted to fit sockets in each of said cakes. The shape of the separating blocks or projections may be varied at will as taste or fancy may dictate. I

Instead of a medical compound Imay insert in the open space between the sections a compound having other qualities of utility. For example, the compound may contain borax, by .which the detergent qualities of the soapmay be enhanced and the cake be thus especially adapted for the laundry or bath-room or be made applicable to various trade purposes. 1

' Having thus described the invention, what I claim as new is l. The improved sectional soap cake herein described, comprising the sections a, b, and

a separating projection holding said sections apart, an'open space being formed betweenwhich extends from one side of the cake to the opposite side, opening through the periphery to receive medicated or other matter, substantially as set forth.

2. The improved sectional soap cake herein described, comprising the sections a, b, one

peripheral edges of the cake, substantially as set forth.

4. The improved sectional soap cake com prising layersor sections of soap held apart by a projection on one of said sections, and a layer of medicated matter filling the space formed between the separate sections, said layer extending out to the periphery of the cake, substantially asset forth.

5. The improved soap cake herein de scribed comprising sections having a projection or projections for holdingsaid sections apart to form a layer-space between, which opens out through the periphery of the cake to form receptacles for useful matter other than pure soap, and cementitious matter for holding said sections together, substantially as set forth.

6. The improved soap cake herein described comprising sections having projections and corresponding recesses, the projections being longer than the depth of the re-v cesses, and cementitious matter for holding the sections together, substantially as set forth.

7. The improved soap cake herein described comprising sections having projections and corresponding recesses, the projections being longer than the depth of the recesses, and cementitious matter compounded with and serving as a vehicle for other useful matter and also serving asa binder for holding said sections together, substantially as set forth.

In testimony that I' claim the foregoing I have hereunto set my hand this 5th day of March, 1900.

LEOPOLD S. SAMUEL.
